PixVerse 5.5: Cinematic Image-to-Video Generation with Sound Sync on playground and API | RunComfy

PixVerse 5.5 is the latest generation of the PixVerse image-to-video model by AiShi Technology, built with an upgraded MVL (Multimodal Vision Language) architecture. Compared to V5 or V4.5, PixVerse 5.5 introduces multi-scene camera transitions, synchronized voiceovers, and audio-visual alignment for narrative storytelling.

Yes, but you must follow the licensing terms specified by AiShi Technology. PixVerse 5.5 is generally released under a Non-Commercial or limited-use license. Using it on RunComfy does not override the model’s original license—commercial deployment of image-to-video outputs requires explicit permission from the model creator.

RunComfy runs PixVerse 5.5 on distributed cloud GPU infrastructure, enabling stable image-to-video rendering with managed concurrency. It automatically scales sessions to minimize latency, allowing multiple video generations in parallel while maintaining consistent quality and response times.

PixVerse 5.5 supports HD resolutions up to roughly 1080p for image-to-video generation. Currently, prompt tokens are capped at around 300, and it supports up to two reference inputs such as ControlNet or IP-Adapter sources. Output durations are limited to 5, 8, or 10 seconds per render.

After testing PixVerse 5.5 in the RunComfy Playground, developers can move to production via the RunComfy API. The API mirrors Playground functionality for the image-to-video pipeline. You’ll need an API key, a valid USD credit balance, and endpoint authentication to automate generation in your app or workflow.

PixVerse 5.5 integrates narrative scene sequencing, synchronized soundtracks, and camera angle variation—all generated from a single prompt. These features make its image-to-video output more cinematic and cohesive compared to competing diffusion-based tools.

On average, PixVerse 5.5 generates a 5-second image-to-video clip in 20–40 seconds on RunComfy, depending on user demand. GPU queues auto-balance workloads so concurrent tasks do not significantly delay completion times.

You hold ownership of your generated PixVerse 5.5 outputs within the limits set by its original license. Even when using image-to-video features on RunComfy, you must comply with AiShi Technology’s distribution and commercial terms. Always verify license type before publishing or selling generated content.

Local deployment of PixVerse 5.5 requires substantial GPU capacity (comparable to RTX 4090 or A100). RunComfy provides managed GPU infrastructure, which is usually more efficient and avoids setup complexity for image-to-video operations. Developers often prefer RunComfy for reliability and scale.

Yes, RunComfy provides free USD credits for first-time users of PixVerse 5.5. After that, image-to-video generation consumes paid USD credits per render. For detailed pricing, consult the 'Generation' section on the RunComfy dashboard or contact hi@runcomfy.com.
